The wide angle Distagon T* 25mm f/2.0 ZF.2 Lens for Nikon F Mount is the most advanced version of the legendary Distagon, a high-performance manual focusing lens with close focus capabilities, first introduced in 1961. The Distagon T* 25mm f/2.0 ZF.2 is a recalculation of this design, with an exceptionally fast f/2.0 maximum aperture, for use with modern SLRs and DSLRs using either full-frame or smaller sensors.
The ZF.2 lenses feature an electronic interface (CPU) which supports all important operating modes such as shutter priority, aperture priority and programmed auto exposure or manual exposure. Manual settings are available on non-AI compatible camera housings. On camera models without an electronic interface, the aperture is manually set on the lens aperture ring.
Increasing the versatility of this 25mm f/2.0 lens is its close focusing distance of only 9.8", providing a wider perspective than usual. Combined with a digital SLR with a 1.5x crop factor, the lens has an effective focal length of 38mm and becomes a moderate wide angle lens.
